"Arianna, my little sister, didn't waste any time when our waitress, Lauren, greeted us at our table," she wrote. "Arianna promptly ordered her cheeseburger with pickles, french fries, and chocolate milk before Lauren could even take our drink order."

But, in spite of her enthusiasm, when the food came, Arianna wouldn't touch the burger because it was cut in half.

"She replied, 'It's broken. I need another one that's fixed,'" MacLean wrote. "Being a child with autism, she has to have certain things in a particular order at all times. One slight change in her routine can change the course of the day instantly."

MacLean explained that to the waitress, who "just smiled and went along with Arianna, telling her 'I brought you a broken cheeseburger?! You know what, I'll have them cook you a new one!'"

The store's manager concurred and the staff brought out another burger, this time fully intact, with extra fries included.

"She let out a big 'OH, I missed you!!' and started kissing the burger over and over again," MacLean wrote.

MacLean snapped a photo of Arianna kissing the burger, which has since lit up the restaurant's Facebook page.

The story of the staff's kindness has received nearly 800,000 likes and more than 186,000 shares.

More importantly, it touched the heart of a 7-year-old.

"Everyone, from the hostess to the chef, played a role in what most people would think isn't a big deal. But this entirely shaped how the rest of our day would go. I know...a cheeseburger cut in half literally could make or break our day. In this case thanks to the professionalism of the crew in Midvale, it made our day."
